Trade-off between Complexity of Structured Tagging and Effectiveness of Web Service Retrieval
نویسندگان
چکیده
Searching for services often starts from the exploration of the service space. Community generated tags can support such exploration. Researchers attracted by the community-available “free manpower” proposed more complex tagging models. Those models tag specific parts of the Web service definition: single operations, their inputs and outputs. However, there is no evidence whether the annotation effort is justified by the performance improvement of retrieval (based on those annotations). In this paper we apply similarity-based search to estimate the trade-off between retrieval effort and the annotation effort. Our experiments shows that exploiting similarity metrics for service ranking can compensate missing information and thus be more realistic solution than passing burden of tagging about more aspects on the community.

Evaluation of Structured Collaborative Tagging for Web Service Matchmaking
Turning Web services into Semantic Web Services (SWS) can be prohibitively expensive for large repositories. In such cases collecting community descriptions in forms of structured tags can be a more affordable approach to describe Web services. However, little is understood about how tagging impacts performance of retrieval. There are neither real structured tagging systems for Web services, no...
متن کاملStructured Collaborative Tagging: Is It Practical for Web Service Discovery?
One of the key requirements for the success of Service Oriented Architecture is discoverability of Web services. However, public services suffer from the lack of metadata. Current methods to provide such metadata are impractical for the volume of services published on the Web: they are too expensive to be implemented by a service broker, and too difficult to be used for retrieval. We introduce ...

Social tagging is a widespread activity for indexing usergenerated content on Web services. This paper summarizes research on folksonomies and their retrieval effectiveness. A TREC-like retrieval test was conducted with tags and resources from the social bookmarking system delicious, which resulted in recall and precision values for tag-only searches. Moreover, several experimental tag-based da...

In responses to Norheim’s editorial, this commentary offers reflections from Thailand, how the five unacceptable trade-offs were applied to the universal health coverage (UHC) reforms between 1975 and 2002 when the whole 64 million people were covered by one of the three public health insurance systems. This commentary aims to generate global discussions on how best UHC can be gradually achieve...
متن کاملStochastic Congestion Alleviation with a Trade-off between Demand Response Resources and Load Shedding
Under the smart grid environments, Demand Response Resources (DRRs) as power system resources can effectively participate in and improve performance of electric systems. Congestion management is one of the technical challenges in which DRRs can play a significant role. Previously, congestion management is applied without considering the power system uncertainties. Therefore, a stochastic conges...
